To ail whom it may concern: a

Be it known that 1, LEE Bownns, a minzen of the United States, residing at {Sherburns, in the county of Chenango andState of New York, have invented. certain new and the calks may be fastened detachably to the shoe. 1

An object of the present invention is the provision of a dovetail groove, which tapers rearwardly, so that every time the shoe comes in contact with the ground the call: is wedged or forced tighter in engagement with the wall of the groove, there being a screw as a precaution to hold the calkin place, and render the same more secure and prevent accidental displacement of the call; forwardly.

\Vhile the design and construction at prescnt illustrated and set forth is deemed pretterable, it is obvious that as a result of a re,-

duction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a bottom plan view of a horseshoe, showing the toe and heel calks as applied thereto.

. Fig. 2 is an enlarged detail perspective viewof one of the heel calks looking upwardly.

Fig. 3 is a transverse sectional view on line 33 of Fig. 1.

Fig. 4 is an enlarged bottom plan view of Fig. 2, showing the walls of the dovetail groove converging toward each other rearwardly.

Fig. 5 is an enlarged detail perspective view of the toe portion of the shoe looking upwardly.

Fig. 6 is a sectional view on line 6-6 of Fig. 5.

Specification ofLetters Patent. I Patented Sept. 2, 1919. Application filed April 12, 1919. .Serial No. 289,520.

Fig. .7 :is a cross-sectional view on line 7.7ofFig.5. w i .1

Fig. 8 is a detail view of the toe call: used in the winter time.

Fig. 9 is a detail view of a heel calkused in the winter time. u 1 Referring more especially to the drawings .1 designates a horseshoe of a conventional design and construction, and 2 denotes the toe calks, which maybe constructed eitherfor winter or sunnner as shown in Figs. 5 andS. In other words, it is obvious that the ground-engaging portion of. either of the calks may be rectangular, or ll-shaped,

as shown in Figs. 5 and 8. The body of the toe call; is rectangular, that is particularly that part designated by the numeral 3 immediately adjacent the shoe, whereby an ordinary wrench may be easily appliedfor removing or applying the calks. For instance, it is the aim to provide calks. for the toe of shoe, which may be easily and quickly applied with a wrench of. ordinary construction. Projecting from the base of the toe calk is a threaded shank 5, which is threaded into an opening 6 of the shoe, utherebysecurely fastening the calk in place,

thatis when the call: is screwed home. It is clear that the toe of the shoe is provided with a pair of calks, and to retain the calks in position, that is to prevent them unscrewing, a retainer plate or an abutment is interposed between the calks. This retainer plate 7 is rectangular, and is secured to the toe of the shoe by means of a screw 8, which passes through the retainer and into a threaded opening 9 of the toe of the shoe. This retainer plate not only retains the calks against accidental rotation or displacement, but also acts as a protector for the calks, particularly since the plate is provided with lateral lugs 10. These lugs 10, it is to be seen, overlie the front walls or faces of the toe calks, thereby not only protecting the bases of the calks, but acting as shields as heel calk 14 has its groundsengaging portion rectangular as shown, and is provided with an integral plate 15. This plate 15 extends forwardly, and is at right angles to the calk. The plate 15 has its edge walls 16 beveled, and said walls converge rearwardly and are designed to engage the beveled converging walls of the flanges. It is obvious, that this heel calk may be arranged between. the flanges. In this case, it is apparent that the plate of the heel ealk will wedge tighter between the flanges, owing to 15 is formed integral with the base of the calk, it is to be noted that the plate is narrower than the base of the .calk. In this case, it is to be seen that the opposite sides of the base of the calk as indicated at 20 overlie the bottom edges of the flanges, and in this way reinforce the calk in position.

The invention having been set forth, what is claimed as new and useful is:

The combination with a heel portion of a horseshoe, the lower opposite corner portions of the heel of the shoe adjacent its extremity having depending elongated flan ges, the adjacent walls of which are beveled, said beveled walls converging rearwardly, said flanges near their rear ends bein thicker than their forward ends and havlng their outer faces flush with the outer side edges of the heel of the shoe, of a heel calk V- shaped in cross-section and having a lower sharpened transverse edge, the upper larger end of the calk having an integral plate at right angles to the call: and extending forwardly, said plate being formed across the upper surface of the larger end of the calk and having beveled edges converging rearwardly and adapted to engage and wedge between the converging beveled walls of the flanges, thereby wedgedly locking the plate between the flanges, where the plate is formed across the upper face of the calk.

said calk underlying and frictionally engaging the bottom edges of the flanges, thereby reinforcing the connection between the calk and the heel of the shoe, the outer side faces of the calk being flush with the outer side edges of the heel, and means penetrat ing the plate and the heel between the flanges, to insure holding the plate in wedged engagement between the flanges.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses. LEE BOYVERS. Witnesses DUANE L. ATKYNs, CHARLES THOMPSON.
